Hello Dave,

thanks for your answer. I agree with you, the easy way is to assign the
rootfs directory. I gave the filesystem as a cpio file because it is the
same (the kernel takes the rootfs and converts it to a cpio format), but
the compilation is faster. Anyway, although now I do as you said, I still
get the error:
"Failed to execute /init
Kernel panic - not syncing: No init found.  Try passing init= option to
kernel."
I can't understand why it happens. I check the permission of /init and
/sbin/init and everything seems to me OK.

Any idea?
